Approximation of reception coefficients of cosmic ray neutron components for latitude measurements

When solving scientific and applied problems such as latitude monitoring, it is important to correctly exclude primary cosmic-ray variations from observational data. At any point in the world, primary variations with an hourly resolution are determined globally by the spectrographic method based on data from the worldwide network of neutron monitors. Therefore, the aim of this study was to develop and implement a monitoring data correction method primarily intended to obtain reception coefficients as a function of latitude. As a result, this provided an approximation of the rigidity dependence of the zeroth and first harmonic anisotropy coefficients of cosmic rays calculated for a ground-based network of cosmic-ray detectors. Analysis of the obtained results showed that the approximation was performed with sufficient accuracy. The results can be used for latitude measurements during marine expeditions and for estimating reception coefficients of new stations in the worldwide network equipped with neutron detectors. In the future, such work will be carried out for stations in the worldwide network equipped with muon detectors.
